Patent FR-2270487-A1 (FR)
Title: Suspension springing for railway carriages - has rubber with stress relieving holes between V-shaped steel plates
IPC: F16F1/40
Filed: 1974-05-07
Abstract: The spring consists of five sheet steel components (11) bent at their mid-point into V sections of angle more than 90 deg. throughout their length, with, vulcanised or glued between them, four thick blocks (10) of either synthetic or natural rubber. To increase the life of the rubber blocks a large circular void (12) is moulded in each for its entire length at the apex of the V, so avoiding the point of highest compression and shear stress concentration.

Title: Anti-spin control for train wheels - with automatic correction for different worn wheel diameters included in central control
IPC: G01P3/489
Filed: 1974-08-28
Abstract: Wheel sped sensors are fitted to the driven wheels of the train, esp. for electric or diesel electric traction where each wheel is fitted with a separate electric motor. The wheel speed signals are differentiated and their acceleration signals are compared by a central control to detect any wheel spin. The respective motor currents are then modulated to eliminate wheel spin. Because of the different wheel diameters through braking and wear a correction has to be applied for each wheel and this is automatically computed by the central control every time the train freewheels, i.e. travels without braking or traction. The stored reference signals are processed in one channel of the two channel control so that accurate spin signals can determined.

Title: Electronic wheel lock prevention circuit - has additional fault finding circuit which produces alarm if system becomes defective
IPC: B60T8/88
Filed: 1975-04-09
Abstract: There is a hydraulic pressure modulator (17), operated by an electromagnet (18) which is mounted in the hydraulic line (13). The magnet is powered by the car electrical circuit (19) and is controlled by the power transistor (20). The electonic logic network (21) receives a signal from the wheel mounted speed sensor (22) and calculates conditions of wheel locking. Under such conditions, it provides a voltage to the transistor base, which switches on the modulator. The effect is to lessen the braking force so that the wheel does not lock up. The logic circuit also provides a constant self check on the system and produces an alarm if a fault is detected.

Title: Activation and revitalisation process for cutaneous tissues - by means of electric fields produced by electrolysis between dissimilar metal wires
IPC: A61N1/24
Filed: 1975-12-31
Abstract: Activation and revitalisation process for cutaneous and sub-cutaneous tissues utilises local electric fields. These are created by the application of supports comprising metals, at definite electric potentials, which are brought into contact with an electrolytic soln., itself in contact with the tissues. A support, in the form of an undergarment, is applied to the surface of the skin with its tissues. The garment comrpises a network of parallel wires, alternately of gold and aluminium; it can absorb the electrolyte and maintain good contact with the external surface of the skin. The electrolyte can consist of perspiration or of a conc. soln. of NaCl, stabilised by a tragacanth gel. Under the effect of the electric field, the Cl anions tend to move from the gold wire to the zone of the aluminium, the Na+ cations migrate in the reverse direction. The skin acts as an osmoti barrier and the passage of the electric charges through the cutaneous tissue is said to have a physiological effect. There is an acceleration of the nutritive exchanges of the cells of the tissues and an elimination of toxins. The penetration of lotions and creams which have previously applied to the skin is increased.

Title: Heat engine using solar energy - having black body solar radiation absorber as evaporator with turbine generator
IPC: F24S10/50
Filed: 1976-05-31
Abstract: Heat engine which uses solar energy has an area which receives the solar radiation and uses it without it being dissipated to the surroundings whether by radiation or conduction. This area forms a black body by being covered with some reasonably economic substance such as minerals, metals or even liquids or semi-liquids by means of which at least those surfaces exposed to the sunlight are blackened. These absorb the solar radiation and release it as thermal energy into a liquid which is fed through passages or lines which lie on or beneath the absorbing surfaces. Insulation of the black body can be achieved by a layer of insulating material below its surface. Device provides an economic means for generating electrical energy.
